TACK OR RIVET SETTER.

I Specification of Letters Patent. Patented Dec. 29, 1914.

Application filed. February 24, 1914. Serial No. 820,571.

To all whom it may concern:

Be it known that I, KEMPE A. MAXWELL, a citizen of the United States, residing at Salem, in the county of Harrison, State of West Virginia, have invented certain new and useful Improvements in Tack or Rivet Setters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to improvements in rivet and tack setters.

The principal object of the invention is to provide a simple hand tool by means of which tacks or rivets may be forced through material and at the same time clenched.

Another object resides in the peculiar construction and arrangement of theparts of the device for holding a tack or rivet which is to be forced through material.

Other objects and advantages will be apparent from the following description, when taken in connection with the accompanying drawings.

In the drawings: Figure 1 is an elevation of my tool. Fig. 2 is an, edge view thereof. Fig. 3 is an enlarged longitudinal section on the line 33 of Fig. 2. Fig. 4 is an enlarged sectional detail of the end of the device showing the same in operative position.

Referring particularly to the accompanying drawing, 10 and 11 represent a pair of crossed pivoted members which are also pivotally connected with and disposed in crossed relation to a similar member 12.

One end of the member 10 is provided with a pin or stud 13 which extends toward the corresponding portion of the member 11 and is arranged to pass through an opening 14 formed in said member 11. Rotatably mounted in the end of the member 11 is a longitudinally arranged screw shaft 15, this shaft carrying a nut 16 which projects through openings 17 in opposite sides of the member 11 so that the same may be gripped with the fingers. The inner end of the screw is rotatably carried in a cross web 18, while secured to the other end of the screw, and disposed adjacent the opening 14 is an approximately M-shaped spring, 19.

The jaw portion 20 of the member 12 is rectangular. in cross sectionso as to'present a flat face against which the point of the rivet or tack is to be bent.

In the operation of the tool a tack is inserted throughthe opening 14 so that the head is in position to be engaged by the stud 13. The spring 19 engages one side of the tack and. holds the same tightly against the opposite wall of the opening 14. The

material to be riveted is placed between the end of the member 11 and the jaw 20, and

upon drawing the handle portions of the members 10 and 12 toward each other the tack will be forced through the material and clenched on the other side of the material against the flat face of the jaw 20.

The primary use of this tool is for attaching half soles to shoes, by passing tacks through the extended edges of the sole and clenching the same on one side. In this connection attention is called to the peculiar arrangement of the aws, this arrangement being such that tacks can be treated in a similar manner but within the shoe.

By rotating the nut 16, the spring 19 is capable of movement toward and away from the opening 14: so that larger or smaller tacks or rivets can be successfully held in the opening 14.

What is claimed is A tack or rivet clencher comprising three crossed members pivotally connected at a common point, the intermediate member having a tack receiving openin formed therethrough, a screw disposed ad acent the opening, a spring disposed to engage a tack,

and a nut carried by the screw for moving the spring toward and away from the tack opening, one of the outer members having a fiat face for bending the point of the tack, and the other of the outer members having a stud disposed in line with the opening of the intermediate member and [arranged toengage the head of the tack and force the same through the said opening.

In testimony whereof, I aflix my signature, in the presence oftwo witnesses.

KEMPER A. .MAXWELL.
